USB Type C – Is It The Future Of USB Interface?


Many people have found a significant change in their mobile phones: more and more mobile data interfaces have been replaced by Type-C. Even Apple, which has been using the lightning interface, seems to have adopted Type-C intent. So why is Type-C so popular?

Certainly, a friend will say, the Type-C interface can be inserted in from both the ends! Yes, this is indeed the most intuitive change brought by Type-C, but in reality, this is only the smallest change it brings. Here are some major benefits of Type-C that we can’t see:-

1. Strong Power Supply

That’s right, it’s about fast charging. It is not difficult to find that the current mobile phones that support fast charging basically use the Type-C data interface. The reason is that it can provide up to 100W of power output, and can be bidirectionally powered through the Type-C interface, both to charge the device itself and to supply power to the external device.

2. The Transmission Speed Is Fast

Some friends will definitely ask here: Is my Type-C mobile phone transmission speed faster than the previous Micro interface? The reason is that most of the mobile phones on the market use the Type-C data interface, but the transmission standard still uses USB 2.0.

USB Version Speed Type
USB 1.0 1.5Mbps Low-Speed
USB 1.1 12Mbps Full-Speed
USB 2.0 480Mbps High-Speed
USB 3.0 5Gbps Super-Speed
USB 3.1 Gen 2 10Gbps Super-Speed+

From the above picture, we can see the transmission speed of different USB standards. The benefit of the Type-C data interface is that it supports USB 3.0 and above. At present, mobile phones supporting USB 3.0 and above are basically positioned in high-end flagships, such as OnePlus 7 Pro, and Samsung Galaxy S/Note series flagship

One thing to note is that even if the phone supports USB 3.1, the data cable that comes with the phone’s original factory does not necessarily support it. For those who have a need for transmission speed, you need to pay attention to the official website to check the parameter list or consult customer service before purchasing

3. Can Transmit Analog Signals

The elimination of the 3.5mm headphone jack has become one of the major trends in the development of smartphones. The Type-C interface has gradually become the connection method for wired headsets. In fact, the Type-C interface and the 3.5mm headphone jack also have something in common. The former can also transmit audio of analog signals.

However, analog signals output by the Type-C interface are susceptible to interference, and more and more manufacturers are beginning to choose digital audio output. So if you want to use a single adapter or Type-C headset, be sure to say if you match before buying.

4. Better Scalability

Type-C can transmit video and audio signals and expand into a variety of audio and video output interfaces, such as HDMI, DVI, VGA interface, and even achieve 4K resolution expansion. The desktop extension function that used the mobile phone as the host before is the embodiment of the video expansion of the Type-C interface.
